U.S. President-elect Donald Trump said on Tuesday he had picked John Ratcliffe, a close ally who was director of national intelligence at the end of his first term, to serve as director of the Central Intelligence Agency.

As President-elect Trump’s team is taking shape, we’re learning more about who will take the lead on energy, climate and the environment. The first announcement on that front is Lee Zeldin, a former GOP congressman who will head the Environmental Protection Agency.

President-elect Donald Trump is moving to build out his national security team, announcing he is nominating Fox News host and Army veteran Pete Hegseth to serve as his defense secretary and former Director of National Intelligence John Ratcliffe to lead the Central Intelligence Agency.

President-elect Donald Trump has chosen Pete Hegseth, a Fox News host and Army veteran, to serve as his secretary of defense. CNN’s Kaitlan Collins and former Republican Rep. Adam Kinzinger discuss.

Hegseth is leaving his co-host role on the weekend edition of 'Fox & Friends' to serve the Trump administration, ramping up the White House-cable news nexus.

President-elect continues his trend of placing loyalists in key positions by naming Pete Hegseth as his choice for secretary of defense and a hawkish former House lawmaker to lead the CIA.
